Sarcasm

First time Penny goes ballistic! Sheldon cleaned her apartment.

Setting their dinner of Thai food, Sheldon gives them a lecture of the use of the fork in Thai history. Penny is in the hallway as they discuss her work at The Cheesecake Factory. She then asks Leonard to sign for a piece of furniture while she is out. They also ask her if they want to join them later for Thai food and a Superman movie marathon. Penny is not sure how many their are, but she does like the one where Superman catches Lois Lane from falling. As Sheldon starts an argument on how that is impossible, Penny seeks off to work.

It turns out the furniture is bigger than they had expected. The delivery man did not help them to carry it, so Leonard and Sheldon was forced to do it themselves. Since they were not physically strong and they have to do it on the stairs, it was hard for them to do the task. Sheldon only idea involves using a Green Lantern power ring. After having a difficult time, they eventually succeed in getting it up the stairs to her apartment. While there, Sheldon sees that Penny's apartment is a complete mess and insists on tidying up, but Leonard said that he should not do that because it is not their apartment. Penny returns soon after. Penny asks if they had any trouble and Leonard told her no.

Later that night Leonard is awakened by sounds coming from outside of his bedroom. Realizing that the door is open, Leonard goes across the hall with his light saber and finds out that Sheldon has used Penny's spare key to enter her apartment to clean. Although initially he is opposed to the idea, he eventually caves in and helps Sheldon clean to get him back.

Leonard get up the next morning and Sheldon tells him that he slept well. Leonard remarks that a well known folk cure for insomnia is to break into your neighbor's apartment and clean. Sheldon asks if that was sarcasm. Penny awakens to find out that her apartment in a well ordered state and screams about those geeky bastards. Entering Sheldon and Leonard's apartment in a fit of rage about coming into her place while she was sleeping. She demands her key back. Sheldon tells Penny that she might want to see a an otolaryngologist about her snoring. "It’s a throat doctor," he explains. Penny then asks Sheldon what kind of doctor would remove a foot from somebody's ass. Leonard holds up a sarcasm sign to let Sheldon know what Penny meant.

Later, Penny runs into Rajesh in the hallway and talks to him about being upset over what happened (although he doesn't reply as he has selective mutism). Penny decides to forgive them while Raj was thinking; "Boy, her hair smells nice" and "Maybe my mother was right. Maybe I should marry an Indian girl. We would have the same cultural background and she could sing the same lullabies my mother sang to me". Penny then hugs Raj, much to his surprise. He then turns his pelvis to avoid embarrassing himself. Later, Leonard tries to apologize with several analogies referencing moments in history where errors in judgment resulted in positive outcomes. Penny cuts him off, and then hugs him saying, "We're okay". Later, the guys help Penny put together her media center, but get so focused on the task that they don't hear her when comments that she's hot and is going to take off her clothes. Soon they get completely carried away and go to the garbage dump to find better materials, leaving Penny to do it by herself and would possibly leave the guys completely embarrassed when they see that she's finished the job herself.

CriticsEdit

  • "A really enjoyable follow up to the pilot. Sheldon’s convictions create a plausible and funny source of conflict for the newly forming group of friends. The writers work really hard here to build a credible world for the characters which feels real and is funny. Long may it continue." - The TV Critic's Review

S01e02fans

Unknown "fans" shirt

Outfitters but has been discontinued. By the final scene in Penny's apartment, Sheldon is wearing a white t-shirt with a pattern of multiple fans. Information on this item would be appreciated.

Leonard starts out wearing a black t-shirt with the molecular structure for caffeine. When Penny's box arrives, Leonard can be seen in a t-shirt from The American Phytopathological Society (a non-profit membership organization dedicated to plant pathology - they make their shirt available to the public, so please support them and buy a couple!). After the blow up with Penny, Leonard sports the "Deter 3" penguins t-shirt from Urban Outfitters. This shirt is discontinued, you'll have to find one used. 

Set NotesEdit

LogiTech

LogiTech iPod station

  • The model of the DC-7 on the bookshelves behind the couch has been replaced with a model of the space shuttle (it turns up later in Leonard's bedroom). New items on the set include a Spirit of St. Louis radio and a LogiTech iPod Audio Station (model S-2017A ), both found on the shelves next to the front door.

TriviaEdit

  • First time it's seen that Sheldon is allergic to bees.
  • First time it's seen that Howard is allergic to peanuts.
  • First time it's seen that Leonard has 2,600+ comic books.
  • First time the inside of Penny's apartment is completely seen. In the pilot Penny is seen standing in it through the and the area around the door is seen from inside the apartment.
  • First time it's seen that Sheldon has possible Obsessive-Compulsive disorder and has trouble understanding sarcasm.
  • Sheldon did not knock his now famous three knocks when he went to apologize to Penny.
  • The book that Leonard picks up in Penny's apartment after carrying up her furniture with Sheldon is 'The Secret' by Rhonda Byrne.
  • When putting Penny's furniture together Howard complains over IKEA's pictographic representation-assemble manual and states that these instructions are why Sweden doesn't have a space program. This statement was true when the episode was aired in 2007. It should be noted that Sweden later have got a highly developed space program.
  • First time it's seen that Penny is shown to be a slob and has a temper.
  • Sheldon says, "Yes, but they all involve a green lantern and a power ring." This fact is a reference to DC Comics Green Lantern, a superhero and intergalactic police officer with a power ring that translates his ideas into green energy using the strength of his willpower and is charged by a Green Lantern Power Battery.
  • Leonard states, "Now we've got an inclined plane. The force required to lift is reduced by the sine of the angle of the stairs, call it thirty degrees, so about half." Sheldon corrects him, "Exactly half." Let \angle_{\mathrm{stairs}} \equiv \theta. \mathrm{Then,} \sin{\theta} \approx \sin{30^{\circ}} = 1/2 is what Leonard sought. Actually, it appears Leonard wanted to say \sin{\theta} \approx 1/2 \ (\mathrm{as} \ \theta \approx 30^{\circ}), \ \mathrm{not} \ \sin{30^{\circ}} \approx 1/2, but already interjected, thus, causing this blunder.
  • Leonard wielding a lightsaber as a weapon and flashlight, upon hearing a noise is a hold-over from the Unaired Pilot.
  • Raj's name is revealed to be Rajesh Koothrappali for the first time.
  • The Petre Devos picture by Xavier Allard in Leonard and Sheldon's kitchen appears for the first time. It would remain from this point on.
  • Arguments about Superman and his powers aren't new. Along similar lines, science fiction author Larry Niven did a great piece called Man of Steel, Woman of Kleenex about the science and challenges surrounding sex between Superman and Lois Lane, as well as how Lois could survive a Kryptonian orgasm (the term "mind blowing" would have a whole different connotation if sleeping with the Man of Steel), or a pregnancy with a superbaby inside her. Great food for thought and debate, from his book All the Myriad Ways.
  • Sheldon mentions the Mandelbrot Setof complex numbers. He's referring to a set of complex numbers; one "real", like normal numbers we're all familliar with, plus one "imaginary number", Imaginary numbers are needed because you can't do things like square a real numbers and get a nagative number, or take the square root of a negative number and get a real number...thus i was invented. It allows for the graphing of fractals and establishing magnitudes, rather than dealing with .actual values. If you're interested in learning more about the Mandelbrot set, fractals, and chaos theory, try reading James Gleick's classic book Chaos, Making new Science

QuotesEdit

Leonard: You convinced me. Maybe tonight we should sneak in and shampoo her carpet.
Sheldon: You don't think that crosses the line?
Leonard: Yes! For God's sake, Sheldon, do I have to hold up a sarcasm sign every time I open my mouth?
Sheldon: You have a sarcasm sign?

Raj: Are there any chopsticks?
Sheldon: No need for chopsticks, this is Thai food.
Leonard: Here we go.
Sheldon: Thailand has had the fork since the latter half of 19th century. Interestingly, they don't put the fork in their mouth, they use it to put the food on a spoon which then goes into their mouth.
Leonard: (To Raj) Ask him for a napkin, I dare you.

(While trying to figure out how to get box with furniture to Penny's apartment)
Leonard: We don’t need strength, we’re physicists. We are the intellectual descendents of Archimedes. Give me a fulcrum and a lever and I can move the Earth, it’s just a matter… (starts to move package) I don’t have this... I don’t have this I don’t have this.
(Sheldon catches Leonard and the box)
Sheldon: Archimedes would be so proud.

Sheldon: Ah, gravity, thou art a heartless bitch.

(The morning after Sheldon has cleaned Penny's apartment.)
Sheldon: I'm feeling so good today, I'm going to choose from the lower fiber end of the shelf. Hello, Honey Puffs.
Penny: (from across the hall) SON OF A BITCH!
Leonard: Penny's up.
Penny: YOU SICK, GEEKY BASTARDS!
Leonard: How did she know it was us?
Sheldon: I may have left a suggestive organizational schematic for her bedroom closet.
Penny: LEONARD!
Leonard: God, this is gonna be bad.
Sheldon: Goodbye, Honey Puffs. Hello, Big Bran.
